NORTHERN SHRIKE.
Notes
January Thirty-first
Hawks, before eating, tear away the skin and feathers from their prey; but owls eat everything, unless the prey be large, even bolting small birds and mammals entire. In the course of a few hours they disgorge pellets of indigestible portions, the bones being encased in the feathers or hair. The pellets may be found on the snow beneath the owl's roost, and they often contain skulls of mice as white and perfect as though they had been cleaned in a museum.
